## ⚠️ Common Signs of Failure

-   Pitted or chipped teeth
-   Excess backlash
-   Bearing, shaft or seal failure after incorrect shimming

## 🛠️ Service Notes

-   Lower gears are supplied and worked on as a matched set — do not mix a new gear with used mating gears, and keep matched bearing pairs together
-   Shim values must be re-established whenever gears, bearings or housings are changed; set tooth backlash and check the tooth contact pattern against the specification for your drive rather than reusing the old shim stack blind
-   This work needs the correct Volvo Penta special tools and measuring gear; without them the gear set cannot be set up correctly and will not last
-   Work clean, inspect the housing bores and bearing seats, and renew the seals and O-rings that are disturbed
-   Fill with the specified lubricant to the correct level, then run the drive gently under light load before working it hard, and check the lubricant for metal afterwards
-   The remanufactured exchange alternative for IPS1 at ratio 1,94/2,08 is 3801714
-   The core criteria have to be met to gain the full advantage of a remanufactured IPS exchange unit - they are set out in the Core Management System (CMS), or ask your Volvo Penta support representative
